The invention provides a power closed-loop real-time simulation test system and a power closed-loop real-time simulation test method. The system comprises an equivalent grid system based on a real-time digital simulator, and an information-power interface circuit. The equivalent grid system sends an analog signal to the information-power interface circuit; the analog signal, after processed by the information-power interface circuit, is sent to a tested physical device to supply power to the tested physical device; an analog feedback signal of the tested physical device is sent to the equivalent grid system through the information-power interface circuit; and the equivalent grid system sends a digital signal to the tested physical device to remotely control a switch in the tested physical device. According to the invention, simulation and test form an organic whole, an advanced technical means is provided for the research and development of novel physical devices, the efficiency of research and development can be increased, smooth transition between sub research and development processes is ensured, problems and defects existing in equipment can be found in the early stage of research and development, and better guidance is provided for equipment research and development.

Description

technical field [0001] The invention belongs to the technical field of power equipment simulation and testing, and in particular relates to a power closed-loop real-time simulation testing system and method. Background technique [0002] At present, simulation technology has fully entered the era of real-time simulation. Real-time simulation has become the development direction of the simulation field because its simulation environment is closer to the actual system. The development of real-time simulation has made digital-physical hybrid simulation possible. , The development of new power electronic devices provides a more flexible and convenient means. [0003] Simulation technology and experimental testing technology are two important technical means for the development of new equipment. At present, the research and development of new equipment still adopts the traditional development process, that is, first theoretical analysis, then offline simulation verification, and ...

AI Technical Summary

Problems solved by technology

Each research and development process is relatively independent, it is difficult to ensure the smooth transition of sub-processes, lack of support from advanced technical means, the research and development process is slow, and the dynamic model test of the low-voltage physical model is difficult to simulate all working conditions of the power grid, and the flexibility is insufficient. The development of new equipment increases uncertainty
